      Ambiguous tests of general relativity on cosmological scales 

      Zuntz, J.; Baker, T.; Ferreira, P. G.; Skordis, C. (2012)
      There are a number of approaches to testing General Relativity (GR) on linear scales using parameterized frameworks for modifying cosmological perturbation theory. It is sometimes assumed that the details of any given ...

(2013)
      Euclid is a European Space Agency medium-class mission selected for launch in 2019 within the Cosmic Vision 2015 - 2025 program. The main goal of Euclid is to understand the origin of the accelerated expansion of the ...

      Modified gravity and cosmology 

      Clifton, T.; Ferreira, P. G.; Padilla, A.; Skordis, C. (2012)
      In this review we present a thoroughly comprehensive survey of recent work on modified theories of gravity and their cosmological consequences. Amongst other things, we cover General Relativity, scalar-tensor, Einstein-æther, ...

      The parameterized post-Friedmann framework for theories of modified gravity: Concepts, formalism, and examples 

      Baker, T.; Ferreira, P. G.; Skordis, C. (2013)
      A unified framework for theories of modified gravity will be an essential tool for interpreting the forthcoming deluge of cosmological data. We present such a formalism, the parameterized post-Friedmann framework (PPF), ...

      Testing general relativity with cosmology: a synopsis of the parametrized post-Friedmann approach 

      Ferreira, P. G.; Baker, T.; Skordis, C. (2014)
      More than half a century after the Chapel Hill meeting of 1957, the landscape of general relativity has been transformed. In relativistic cosmology we are entering an era in which we can seriously consider testing some of ...
